cuAao ATTACHMENT FOR CASH-REGISTERS.

SPECIFICATION forming part .Of Letters Patent N 0. 674,381, dated May 21, 1901.

. Application filed July 2'7, 1900. Serial No. 24,976. (No model.) I

To all whont it may concern.-

Be itknown that LEMIL FRANK'HAENCHEN,

, new and useful-Improvements in Guard Attachments for Cash-Registers, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar characters of reference indicate corresponding parts.

This invention relates to improvements in guard attachments for cash-registers; and the object thereof is to provide a device of this character which is adapted to prevent tamporing with the interior operating and indicating mechanism of the apparatus.

The invention will be hereinafter fully described, and specifically set forth in the annexed claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a crosssectional elevation of part of a cash-register having my improved guard attached thereto, and Fig. 2 is a perspective view of theguard detached from the machine.

In the practice of my invention it is used in combination with any cash-register of the lever-and-key-operated variety. In thisclass of registering-machines it has been found that a fine wire inserted at 1, between the key or operating levers 2, can be employed by clerks or others to surreptitiously derange the registering mechanism for the purpose of preventing registration and defrauding the proprietor of the apparatus. To obviate this practice), I employ a sheet-metal guard A, which embodies a fiat base portion a and an extended convex portion a, formed integral with each other. The base a of this said guard is provided with screw-holes a for reception of the fastening-screws 3, which are employed to secure the device to the bar 4 of o the cash-registering machine.

I do not confine myself to the use of my invention in combination with any specific form of I cash-register, and I reserve the right to vary the contour of the device in accordance with requirements of various machines to which it may be attached.

The operation and advantages of the device are obvious, being permanently placed acrossthe path of the slots in which the operating-levers swing and in front-of the indicating mechanism, a wire inserted through any of the said slots will simply be bent and guarded by the convex surface of the guard in either a downward or upward direction away from the mechanism.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

In a cash-register, the combination with the bar 4, of said register; of the metal plate A, comprising the fiat base Cb, pierced with the screw-holes a and the convex portion a, said parts a and a being integral with each other,-'

and together forming said plateA; and screws 3, extending through said screw-holes, and attaching said metal plate A, to said bar 4, within said register, across the key slots thereof; all substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 21st day of July, 1900.
